'I'his invention concerns a clasp or clip for forming waves in the hair,that is, for arranging, giving form to and holding hair waves, havingsides pressed on to each other lengthwise under the influence of aspring, which sides are provided with lower edges curved according tothe shape of the head and inner rows of teeth lying opposite to oneanother, but taking up their position in gaps, and further provided withiinger gripping members for opening thel clasp.

According to this invention the teeth are so formed and are disposed insuch a position on the sides of the clasp, that the longitudinaldirection of each tooth is obliquely disposed in relation to the curvedline connecting the bases of the teeth of a row.

A further characteristic of the invention lies in the fact that thesides of the clasp are bent in a. lateral direction.

In order'that my invention may be better understood, reference may bemade to the accompanying drawings, in which Fig. .1 shows hair `waves asthey are formed on the head, naturally or artificially; Fig. 2 is apartly broken side elevation of one embodiment of the improved clasp;Fig. 3 is a plan of the iirst embodiment, as viewed from above, in Fig.2; Fig. 4 is a front elevation of the same, in closed position; Fig. 4ais a transverse section, with the hair wave secured, the section beingtaken upon the line IVw-IVa of Fig. 8, looking toward the left, in Fig.8; Fig. 5 is a view corresponding to Fig-4, with the parts shown inextended position; Fig. 6 shows in plan a second embodiment; Fig. 7 is aperspective view of the same; Fig. 8 is an elevation corresponding toFig. 2, with further parts shown in dotted lines;

, Fig. 9 is an underside plan of the embodiment shown in Figs. 2 to 5,inclusive, and Fig. 8; Fig; 10 is a section corresponding to Fig. 4a,but looking toward the right in Fig. 8; and Fig. 11 is an underside planof the modification shown in Figs. 6 and 7..

- In Fig. 1, the ridges of the crests of the waves are marked A-B andC-D. The hair, as clearly shown in this Fig. 1, runs at an oblique angleto' these ridges A-B and C-D, not perpendicular thereto. With the knownforms of clasp, the

` teeth on the sides are so formed, and-are disposed on the sides insuch a position, that the longitudinal direction-of the-teeth runsperpendicularly, orl approximately so, tov the curved, connecting baseline. When such a clasp is applied to a hair wave in the usual way, theteeth thereof, at their gripping points, force the hair out ofvitsnatural, oblique, illustrated position in relation to the direction ofthe ridge A-B or C-D, with the result that the wave arranged or formedby the clasp becomes distorted.

With the embodiment according to Figs. 2 to 5, each of the twolengthwise extended sides or 5 jaws 3--4 of the clasp with theiingergrips 10-'11 disposed thereon, is made from sheet metal. Thesesides or jaws are connected together by means of` a pin 5 which passesthrough holes in lugs 6 bent over from the hand grips. 'I'he edges 10 ofthe clasp sides 3-4 are curved to conform to the shape of the head and arim 12 is bent back Aoutwardly from the extremity of each clasp sidealong a curved line '1. A. spring 8 fitted around the pin 5 tends topress the sides 3-4 against 15- each other.

y In the curved line 'l of each of the clasp sides 3-4 are disposed thebases of the teeth 9-9a. The teeth 9-9a which are pierced from the clasplsides are'bent back inwardly thereof in such a 20 way that thelongitudinal direction of eachtooth runs obliquely in relation tc theline '7, so that the line of projection from the reduced extremity ortip of any tooth-intersects the line of its base outside the base of thetooth. The teeth of both 25 sides are so disposed in relation to eachother that when the clasp is in its closed position, the teeth of theone side engage in the gaps between the teeth of the other side and withthe teeth near the vouter ends bearing on the outwardly 30 bent rims 12(Figs. 4and 10). In the closed position, the extremities of at leastsome of the teeth 9-9a project beyond the lower edge of the sides 3 or 4against which they lie, which edge is curved to the shape of the head(Figs. 2 and 8). The 35 object of this construction is to enable quiteshort hair to be secured by the clasp.

When the clasp is seen in side elevation, as in Figs. 2 and 8, the lineof projection 14 (Fig. 8) from the tip of any tooth of a row intersectsthe 40 line connecting the bases of the teeth at a point outside thebase of the particular tooth. In the closed position of the clasp, as isparticularly shown in Figs. 2 3, and as seen in edge view from below inFig. 9, the line of projection 15 (Fig. 9) 4U from the tip of anyparticular tooth of the row of one side intersects the line connectingthe bases of the rows of lteeth on the other side of the clasp 'atapproximately the beginning of the the base of an adjacent tooth in thelatter row.

As is shown in Figs. 4, 4a and 10, the sides 3-4 of the clasp, when theclasp is in closed position, do notfcontact at the base line '1 of theteeth, but are held vapart by the contact of the teeth with the rims 12,and the sides are also spaced the clasp is closed, lie at an angle suchthat the sides converge from the back edges to the base line of theteeth.

When using the clasp, the finger grips sides 10-11 are pressed togetheragainst thepressure of the spring 8, whereupon the clasp opens and theteeth 9-9a are set apart from each other. The clasp is then xed on ahair wave at the point of a wave crest, that is to say, along the ridgeA-B or C-D of such a wave (Fig. 1) Then the grips sides 10-11 are slowlyreleased so that the teeth 9-9a, engage in the hair in such a way thatthey are,y disposed approximately in the direction of the hair lyingobliquely in relation to the direction of the ridge of the wave.

By virtue of the fact that the teeth 9-9a, running obliquely in relationto the curved line 7, engage in the hair in the same direction as thehairl itself takes, the position and fall of the hair are not disturbed,and, by virtue of the fact that the sides 3--4 of the clasp lie neartogether only on the curved line 7 and are set apart outy side the line,the possibility of spoiling the wave or pressing it fiat is alsoavoided.

Thus the waves, as far asytheir maintenance is concerned are notdetrimentally affected by the use of the new clasp from the standpointof airiness (ventilation) and looseness but are for the rst time giventheir correct form and are thus advantageously influenced, as is shownparticularly in Figs. 4a and l0.

Owing to the oblique position of the teeth as illustrated and described,in comparison iwith clasps of the known types, in which the teeth runvertically in relation to their base line, considerable advantagesaccrue from the use of this clasp. The hair is held considerably moresecurely by means `of the clasp and an unintentional loosening of thehair from the teeth of the clasp is rendered difficult.

According to the second embodiment (Figs. 6, 7 and 11) ofthe invention,the clasp sides 3-4 are bent in such a manner that the line 7 in whichthe base of the teeth 9-9a are set, is curved in two planes that is tosay longitudinally as shown in Figs. 2 and 8 and laterally as shown inFigs. 6 andll, whereby the arrangement or holding of hair waves runningin a curve is made possible.

The clasp may be modified in various respects in relation to theembodiment illustrated and described. For example, the teeth, instead ofhaving a at surface, may be given any other desired and suitable form;for instance, they may have a slight undulation, and at the ends,instead of being pointed, they may be rounded off.

Instead of the ends of all teeth, when closed, projecting over the loweredge of the clasp side against which they lie, their Aforrn may be suchthat the ends of only certain teeth project over the lower edge.
